Abstract
A bed mat having a sensor for detecting abnormally high temperatures and for detecting when the occupant of the bed is not in it is connected to a control console which has circuits for producing a first electrical signal having a first characteristic in response to the detection of an abnormally high bed temperature and a second signal having a second characteristic in response to the detection of the absence of the bed occupant. In one form of the invention, these signals are applied to the conventional nurse call system to produce sensory signals at the nurses' station, for example, indicative of the detection of high temperature or absence in a way such that they can each be distinguished from the signal produced at the nurse's station by the use of the nurse call button by the patient. Provision is also made for coupling of a smoke detector into the system for actuating the high temperature alarm signaller if smoke is detected.
